Abstract
An infrasound generator including a quarterwave resonator tube having a closed end and an open end and being of substantially uniform diameter, the open end of the tube being adapted to communicate with a space containing the heat exchange surfaces of a boiler through an aperture in a wall of the space and having means for supplying pulsating pressurized air to the closed end of the resonator tube. An outwardly opening conical diffuser is connected between the open end of the resonator tube and the space and a sleeve extends back from the wall and surrounds at least a portion of the length of the tube, the sleeve being of greater diameter than the tube with resilient closure means connected between the diffuser and the sleeve.
